(01. 126-190) This invention relatesto stoves adapted for burning hard fuel and has particular reference toa novel and efiicient manner of introducing fuel into the combustionchamber in such a Way as to eliminate substantially the escape'of smokeand fumes from the combustion chamber into the space in which thestove-is arranged at such time.

A principal object of the invention, therefore,

is to provide in a stove adapted for burning hard fuel a means forintroducing fuel into the combustion chamber in such a manner so as tosubstantially prevent the escape of fumes and smoke from the combustionchamber through the fuel feed door opening.

Other and further objects of the invention will be apparent from thefollowing description and claim and will be understood by reference tothe accompanying drawings, of which there are two sheets, which, by wayof illustration, show a preferred embodiment and the principles thereofand what I now consider to be the best mode in which I have contemplatedapplying those principles. Other embodiments of the invention embodyingthe same or equivalent principles may be used and structural changes maybe made as desired by those skilled in the art without departing fromthe present invention and the purview of the appended claim.

In the drawings:

Fig. 1 is a front elevational view of a stove embodying my invention;

Fig. 2 is a fragmentary sectional view taken in a plane along the line2-2 of Fig. 1, looking in the direction of the arrows;

Fig. 3 is a view similar to Fig. 2 but with the fuel feed door in openposition;

Fig. 4 is a view similar to Fig. 3 but showing the position of the fuelfeed door and closure during closing movement; and

Fig. 5 is a fragmentary horizontal sectional view taken in a plane alongthe line 55 of Fig. 3, looking in the direction ofv the arrows.

In Fig. 1 a stove embodying my invention is illustrated. This comprisesa stove adapted for burning hard fuel and includes an opening l0adjacent the upper end thereof and a pivoted door I 2 provided with anoperating handle [4. The door 12 may be made of any suitableconstruction and is hinged for movement between the position illustratedin Fig. 2 and that illustrated in Fig. 3 on a pivot IS. The opening incomprises aligned openings in the outer and inner panels 18 and 20 ofthe stove body or cabinet. Each side of the door I2 is provided with anmovement of the door l2.

inwardly extending flange 22, each of which is provided'with a laterallyextending lug 24 which cooperateswith the edge of the opening H3 in thepanel 20 for'li miting the outward opening I The door I2 at its top andsides is provided with an inwardly extending flange 26 which abuts theouter surface of the wall 20 around the opening [0 when the door isclosed so as to effectively seal the opening it! through the panel orwall 20.

A closure member'28 in the form of a receptacle presented toward theopening I0 is hinged inside the stove on the pivot 30 for movement abetween the positions illustrated in Figs. 3 and 4;

This member 28 includes spaced walls 32 connected by curved wall 34; Themember 28 thus is open toward the opening it] as well as downwardly.This member 28 is pivoted in the upper part of the combustion chamber36.

The front and bottom edges 38 and 40 of the walls 32 cooperate withflanges 42 and 44 and the free edge 46 of the member 28 cooperates withthe flange or chute 48 to form a closure for the opening l0 interiorlyof the combustion chamber 36. The flanges 44 and 48 form a chute whichextends inwardly and downwardly from the opening l0 and the panel 20 andcooperates with the member 28 when arranged as illustrated in Fig. 3 toprevent the escape of smoke and fumes from the combustion chamber 36through the opening in when the door I2 is open.

Each of the side walls 32 of the member 28 is provided with a pivoteddog 50 in the form of a bellcrank pivoted at 52. With the door l2 in itsclosed position, as illustrated in Fig. 2, the lugs 24 on the sides 22of the door l2 are positioned below the dogs 50 and during openingmovement of the door the dogs are free to swing in a counterclockwisedirection about their pivot 52, thereb permitting free opening movementof the door without any corresponding movement of the closure 28.

When the door arrives at its open position, as illustrated in Fig. 3,the lugs 24 will have moved to such an extent so as to permit the dogs50 to assume the position illustrated in Fig. 3. In this position an ear54 of each of the dogs cooperates with a lug 24- so as to maintain thedog 50 in the position.

Upon closing movement of the door, the lugs 24 reacting on the ends ofthe dogs 50 in the manner as illustrated in Fig. 4, will cause theclosure 28 to swing in a clockwise direction so as to permit the lu s 24to clear the ends of the do s 50 and return to their position asillustrated in Fig. 2.

The other ends of the dogs are formed to engage the wall 34 so as tolimit their clockwise rotation.

As soon as each of the lugs 24 has moved through an arc sufficient toclear the end of the dog against which it is bearing, as illustrated inFig. 4, the closure member 28 will swing back to its position asillustrated in Fig. 2, the mass of.

the closure 28 and its side walls and the center of gravity "being-sorelated to the pivot 30 that the closure 28 normally assumes theposition illustrated in Figs. 2 and 3.

It will thus be observed that when the door [2 position thereof forclosing said opening, a chute projecting inwardly from said opening,said clois opened, the closure 28 prevents the escape of smoke and fumesfrom the combustion chamber into the room. When the door 12 is open, thedoor [2, chute 48, and closure member '28 form a hopper adaptedtoreceive fuel. During the closing movement of the door l2, as illustratedin Fig;

4, the fuel in the hopper provided by the door l2,

the chute 48 and the closure 28 will be automatsure in its open positioncooperating with said chute so as to accommodate a charge of fuel, amovable inner closure pivoted to said stove adilacent said opening andcooperable with said "chute for automaticall closing said opening on Vthe inside thereof, said outer closure having lugs ically dischargedinto the combustionachamber 36 through the ap created. .bythe inwardmovement of the closure member 28. I While theicom- 'bustion chamber3.6. is open to the room, atthis time, the time interval is very smalland the fuel feeding into the. combustion chamber 35. from theh0pper,.as. previously described, will tend to,

eliminate any flow of smoke. or fumes from the combustion chamberBB intothe room.

Theinside of the outer door or closure 12 is on thexinner side thereof,dogs pivoted to said inner closure and arranged at the sides thereof andin the path of movement of said lugs during movement of said outerclosure from open to closed position whereby upon closing movement ofsaid outer closure said lugs will engage said dogs and thereby move saidinner closure to its open position, said closures and the lugs and dogscarried thereby being constructed and arranged so that after theinnerclosur-ehas been opened said lugs will disengage themselves from saiddogs whereby to permit said inner. closure to close and bevcloseol whensaid'outer closure has completed its closing movement, the pivotalconnection of said dogs on said inner closure permitting said lugs totemporarily displace said dogs upon opening movement of said outerclosure without a corresponding movement of said inner closure.
